Russian airline Aeroflot was forced to cancel more than 50 round-trip flights on Monday, disrupting travel across the world's biggest country, as two pro-Ukraine hacking groups claimed to have inflicted a crippling cyberattack.

The hack may have been part of a campaign to disrupt the sense of normalcy Russians have mostly enjoyed since the start of the war.

On 28 July, the hacker group Silent Crow, in cooperation with Cyber Partisans BY, breached Aeroflot's [Russia’s largest airline – ed.] internal IT infrastructure and destroyed around 7,000 physical and virtual servers.
